On Next, you generally cannot change an order once it has been placed due to their efficient processing system.
Understanding Next's Order Amendment Policy
Next prioritizes quick delivery for all customers. To achieve this, their order processing system is highly automated and fast. This means that once you have confirmed and placed your order, it quickly moves into the fulfillment stage, making modifications extremely difficult.
Why Changes Are Not Possible
Next explicitly states, "we're unable to change your order once you've placed it." This policy is in place because they "process orders quickly so that your items arrive as soon as possible." The speed of processing leaves very little to no window for adjustments after an order has been submitted.
The Only Exception: Cancelling Delayed Items
While changing an order is not possible, there is one specific exception mentioned by Next. If an item in your order is experiencing a delay, you may have the option to cancel just that particular delayed item. This is the only scenario where a modification to an existing order (specifically a cancellation of a part of it) might be permitted.
